Perhaps your question is
"I want to know how to use a squat toilet,
and I would prefer the explaination to be
in the form of cartoon figures."
See this page,
which I would guess is from a hostel in India.

What if you want to ask "Where is the toilet?" in some
other language?
Ask the Travlang.com site.
I have received complaints that they don't list enough languages (!!)
or that the precise semantics for the Farsi is a bit off (!!!),
but complain to them and not to me.

Jochen Zeh was working on an art project that would
"draw a line made of sparkling white toilets into a green,
hilly field of upcoming wheat"
in Tuscany.
All he needed was:
"Somebody who will lend me 200 toilets for one or two weeks.
A photographer specialized in landscape and architectural photos.
A magazine who will publish the photos."
Unsurprisingly, this project seems to have failed.
It was once discussed
here
and
here
but the entire jochenzeh.com domain has disappeared
along with this nutty idea.

Four physicists at Brigham Young University studied
the physics properties of urine splash-back in a
urinal-like environment.
Fluid dynamics revealed
how to minimize urine splash-back.
Summary: closer is better, as fluid streams follow the
Plateau-Rayleigh instability and break up into a
stream of drops, each with individual splash-back.
Angle also helps.

Law of Urination:
all mammals empty their bladders over the same
duration, approximately 21 seconds, despite bladder
volumes ranging from 100 milliliters to 100 liters.

"Dogs
are sensitive to small variations of
the Earth's magnetic field",
a paper in Frontiers in Zoology 2013, 10:80,
by scientists from the Czech University of Life
Sciences and the University of Dulsburg-Essen.
Their abstract contains: Several mammalian species spontaneously align their
body axis with respect to the Earth's magnetic
field (MF) lines in diverse behavioral
contexts. [...]
We measured the direction of the body axis
in 70 dogs of 37 breeds during defecation
(1,893 observations) and urination (5,582
observations) over a two-year period. [...]
Dogs preferred to excrete with the body
being aligned along the North-south axis
under calm MF conditions. This directional
behavior was abolished under Unstable MF. The
best predictor of the behavioral switch was
the rate of change in declination, i.e.,
polar orientation of the MF.

The Powerful History of Potty Training
in The Atlantic discusses sociopolitical
aspects of toilet training.
Authoritarian collectivism of East Germany,
uninhibited lassez-faire in leftist West German
Kommunes,
the belief by 1940s American anthropologists that
Japanese early toilet training directly led to
"the overwhelming brutality and sadism of the
Japanese at war",
Freudian inspired theories that authoritarian German
toilet training led to robotic obedience to authority
and anti-Semitism in the 1930s and 1940s,
and more.

BBC reported
that Hong Kong police had raided
triad gang-run brothels operating out of
converted public toilets
in an unused shopping mall.
"Many of the women held are thought to be from
mainland China.
[....]
In a statement, Hong Kong police said they
arrested 51 women and 35 men aged between
17 and 72.
Drugs, knives and other illegal objects were
seized during the raid.
Local media reports said that the brothels had
been running for several months and that male
and female toilets had been converted into
11 sq m (120 sq ft) cubicles used for
sexual activity."

What Makes a Good Toilet
in The Atlantic discusses pit toilets and
their effect on local health and culture,
especially in Africa and other places where
the U.S. Peace Corps works.

The horrors of the lack of plumbing in the
European Dark Ages through Medieval times.

The first patent for a flushing toilet, awarded to
Scottish
inventor Alexander Cummings in 1775.

The 19th century English plumber coincidentally named
Thomas Crapper, who did a lot to popularize
the flushing toilet but did not invent it.

Time magazine had
a story in March 2009
about a toilet-themed restaurant in Taiwan.
"Modern Toilet" it's called, and it's now a chain with seven outlets
in Taiwan, one each in Hong Kong and Shenzhen, and plans for others
elsewhere in China and in Macau and Kuala Lumpur.

A new
toilet-themed restaurant
opened in Taiyuan, Shanxi Province, China in
Seeptember, 2013, joining Beijing, Shanghai,
and Hangzhou which all had their own by then.
Many pictures
are available.

In the build-up to the Olympic games in Beijing,
according to the BBC in March, 2008:
"China is rushing to install sit-down loos for its 500,000
foreign Olympics visitors, after complaints that venues had
only Asian-style squat toilets.
A lack of Western-style facilities was a common complaint after
some 30 test events at Games venues, officials said.
'A lot of parties have raised the question of toilets... We have
told the venues to improve on this,' said Yao Hui, deputy head
of venue management."
Yikes, a lack of raised porcelain commodes!
Much worse than China's awful human rights record, no?

The Internet holds umpteen copies of a story about a US Navy air mission
against Vietnam.
They were running short of ordnance but at the same time commemorating
the 6-millionth pound of ordnance dropped (well, if you're dropping it
by the millions of pounds, you're going to run out before long).
A toilet had been damaged on board the USS Midway, and was going to
be thrown overboard.
The ordnance crew made a rack, tailfins, and nose fuse for it,
and it was mounted on an A-1 Skyraider of VA-25.
It was then dropped in the Delta area of South Vietnam.

Buying and Repairing Toilet Hardware and Related Items

Answering the question, "But what if my existing toilet provides
inadequate radiological contrast when the patient eliminates waste
in a normal position?"
and introducing the obscure term defecography:
Build your own radiological commode!
There used to be one of those for sale at

but that domain has disappeared.

On the other hand, if your question is more like
"But what if I am so grotesquely obese that I need
a specially designed toilet to support my quivering bulk?",
then check out the
Big John Toilet Seat and Support Company.
Their toilets are tested to a weight capacity of a
a 1,200-pound load!
And by "1,200-pound load" they mean over a half-ton of flesh
upon its extra-wide seat, and not, ah, you know what I mean.
They seem to have taken the market niche formerly held by the
Great John Toilet Company, which marketed a unit tested to
a full ton, 2,000 pounds!

My cromwell-intl.com domain appeared in September, 2001,
although the Wayback Machine didn't notice its one enormous
Toilet of the World page until
January 17, 2002.
Some time soon after that I split it into categories,
and the collection has grown ever since.

In December, 2010 I registered the
toilet-guru.com
domain and moved the pages to a dedicated server.
